基于绿色交通的市政道路改造策略研究

Research on Municipal Road Reconstruction Strategy Based on Green Transportation

摘要: 以某市XX主干道为对象，本研究构建面向绿色交通的道路改造体系，涵盖路权重构、低碳设施升级与智慧化管理，并建立以通行效率、碳排放、出行体验为核心的量化评估。改造在断面上统一拓宽非机动车道至3米并设置缓冲与隔离，实施早高峰专用公交道与受保护式骑行过街，设施侧配置直流快充与交流慢充、太阳能LED照明与暖拌再生路面，管理侧部署自适应信号、公交优先与占用治理。实测表明，早高峰旅行时间由15分钟降至12分钟，降低20%；道路CO₂排放强度由120降至90克每公里每标准小汽车单位，降低25%；非机动车道满意度由60分升至78分，提升30%。结果验证了以公交和慢行优先为骨架的综合策略可在既有主干道条件下显著压降延误与排放并改善出行体验，具备可复制推广价值。

Abstract: Taking XX main road in a city as the object, this study constructs a road reconstruction system for green transportation, covering road right reconstruction, low-carbon facilities upgrading and intelligent management, and establishes a quantitative evaluation with traffic efficiency, carbon emissions and travel experience as the core. In the reconstruction, the non-motor vehicle lane is uniformly widened to 3m on the cross section, and the buffer and isolation are set, and the bus lane dedicated to the morning rush hour and the protected riding crossing street are implemented. The facility side is equipped with DC fast charging and AC slow charging, solar LED lighting and warm mixed recycled pavement, and the management side is equipped with adaptive signals, bus priority and occupation control. The actual measurement shows that the travel time in the morning rush hour is reduced from 15 minutes to 12 minutes, a decrease of 20%; Road CO₂ emission intensity is reduced from 120 to 90 grams per kilometer per standard car unit, a decrease of 25%; The satisfaction of non-motor vehicle lanes increased from 60 points to 78 points, an increase of 30%. The results show that the comprehensive strategy based on bus and slow-moving priority can significantly reduce the pressure drop delay and emission and improve the travel experience under the existing main road conditions, and has the value of replication and promotion.
